Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study is a randomized, double-blinded, placebo-controlled trial with 40 patients in each group: 2 mg melatonin, 10 mg melatonin and placebo. The primary outcome is anxiety reduction in patients before undergoing the procedure. The primary outcome is measured by visual numerical rating scale for anxiety and the Amsterdam Preoperative Anxiety and Information Scale. Based on the results of previous studies, the investigators hypothesize that melatonin may reduce anxiety in patients undergoing the procedure and be a suitable alternative to intravenous sedation in the pain clinic for patients undergoing lumbar medial branch blocks.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Many patients experience anxiety before the LMBB procedure and require intravenous midazolam or fentanyl for sedation. In fact, in a retrospective review of over 8,000 interventional fluoroscopically guided pain procedures, the highest incidence of vasovagal episodes occurred with LMBB procedures. A nurse is required to administer these medications and monitor patient's vital signs. In addition, recovery from these medications can unduly prolong the patients visit and, in the case of fentanyl, can confound the diagnostic utility of the LMBB procedure by decreasing patient's pain.
In an effort to minimize the cost of administration, monitoring, time of recovery and maximize the diagnostic utility of LMBBs, a suitable alternative is required. Several randomized, double-blinded, controlled trials investigate the anxiolytic effect of melatonin before a surgery. Several other studies and review articles describe the use of melatonin for both sedation and anxiolysis in both adults and children. However, no studies to date describe the use of melatonin for anxiolysis or sedation for interventional pain medicine procedures.
Melatonin ((N-acetyl-5-methoxytryptamine) is an over-the-counter product which patients can take to reduce anxiety before a procedure; it is a hormone produced in the pineal gland and secreted into the blood and cerebrospinal fluid. Melatonin has several functions including the regulation of circadian rhythms and regulation of the reproductive axis and antioxidant activity. Exogenous melatonin has been used to treat insomnia and jet lag.

2 mg Melatonin
To remain within the doses used for anxiolytic effects in past studies, we plan to study the effects of 2mg melatonin.
2 mg Melatonin
40 patients will randomly receive 2 mg melatonin
10 mg Melatonin
To remain within the doses used for anxiolytic effects in past studies, we plan to study the effects of 10mg melatonin.
10mg Melatonin
